Fast and robust in vivo B1+ mapping is an essential
prerequisite for multi-element transmit applications
like RF-shimming and transmit SENSE. DREAM, a recently
introduced B1+ mapping approach, is very fast and
promising, allowing single shot B1+ mapping within a
fraction of a second. However, DREAM might be sensitive
to flow which potentially degrades the B1+ maps for the
blood pool signal in large vessels and in the heart. In
the present work this has been solved successfully by
adding an efficient and robust magnetization preparation
approach which is studied in detail here for high field
applications.
